I finally pulled the trigger on the R6 II last week and honestly I'm broke now lol. That body plus the glass really ate into my savings but I needed the upgrade for some freelance work I have coming up. I'm doing this multi-day music festival thing next month in Chicago and I'm stressing about the storage situation because my old UHS-I cards are basically paperweights for the 4K 60p stuff I want to do. I really want to lean into the C-Log 3 and 10-bit recording but the file sizes and bitrates are kinda intimidating for someone who used to just shoot 1080p.

Right now I'm stuck between a few choices. Option one is the ProGrade Digital V60 cards, the Gold series ones. I can get a 256GB for a decent price, which would be great for not having to swap cards every twenty minutes during a set. But then I see everyone saying V90 is the way to go for the R6 Mark II if you're doing any serious video. So option two is the SanDisk Extreme Pro V90, but man, the price jump is insane. For my $180-ish budget I can either get a massive V60 or a tiny 64GB or 128GB V90. I've also seen some people mention the Sabrent Rocket V90 cards being a bit cheaper but I've never used that brand before and I'm nervous about losing footage at a live event.

I've been reading the manual and it says for 4K 60p IPB you need a certain speed class but then people online say the buffer fills up fast if you dont go top tier. I'm mostly worried about the camera overheating or just stopping the recording in the middle of a song because the card couldnt keep up with the data stream. If I'm mostly sticking to the standard 4K 60p (not the RAW external stuff), can I actually get away with the V60 ProGrade or am I just asking for a headache later on?
